Home Alarm System Prototype
May 2020 – September 2020
• Over the summer of 2020, I designed
circuitry and programmed an ATmega328P
to function as a home alarm using a
pyroelectric motion sensor. My main
objective with this project was to become
comfortable with interrupt service
routines, microcontroller interfacing with
external devices (like an LCD screen), and
continue to practice writing firmware in
embedded C.
